Haybail acts like cactus

Hey guys so far Iv'e only noticed one bug so far when a baby or baby donkey gets in a haybail they die like a cactus trait I thought that was really weird and Oh and if you haven't seen my Minecraft 1.6 Horse bugs check it out. Hope this kinda informed you about the haybail bug I found it quite annoying xD and please comment and tell me what you think. :]
